Abstract: ABSTRACT         The invention concerns a process for recovering uranium and/or aluminium from a refractory silico-aluminous material.   The silico-aluminous material is leached in one or more stages to give a pregnant solution which contains little or no acid that would inhibit the recovery of the uranium and/or aluminium from the leach solution.  Generally the pH will be in the range of about 1,5 to 2 so that the maximum amount of free acid will be about 5 grams per liter.          The desired materials are recovered from the leach solution.

Abstract: LOW PROFILE PROSTHETIC XENOGRAFT                    HEART VALVE                       Abstract Prosthetic heart valves having a low profile are disclosed which comprise an annular, right cylindrical, metal stent covered with fabric around which a glutaraldehyde-stabilized pericardial valving element is attached.  The valving element is formed of three leaflets, each having a plateau on a truncated triangle extending higher at the center than at the edges, and formed as a cylinder having a diameter substantially equal to the diameter of the stent.  In a preferred embodiment of the invention, the stent has upright legs which have radiused upper tips which are approxi-mately one-half the width of prior art stent legs. These narrow tipped stent legs reduce stress induced in the leaflets by curvature of the leaflets around the tips of the stent legs in the closed position, extending the service life of the valve.  Tabs are added to the tips of the stent legs to add structural strength.  These tabs can be tapered or straight but their bottom portions must be narrower than the stent legs.  The tabs have a plurality of holes in them through which coaptation stitches are passed.  The coaptation stitch can be two separate stitches, one in a first plane and one in a second plane at 90° to the first plane, or, in the preferred embodiment, a single figure eight stitch passing through the holes in the tab in a plane coincident with the long axis of the stent leg.

Abstract: METHOD AND APPARATUS FOR INOCULATING CRYSTALLIZATION SEEDS INTO A LIQUID LATENT HEAT STORAGE SUBSTANCE            Abstract of the Disclosure Method and apparatus for inoculating a liquid latent heat storage substance of the type convertible to the solid state on cooling.  A portion of the substance is caused to crystallize on a cooled active surface, immersed in the substance and preferably vertical, whereupon the active surface is heated to fuse-off the formed crystals to release same into the liquid portion of the storage substance to thus form inoculation seeds on which further crystallization of the storage substance takes place on withdrawal of heat from same.  In one described embodiment, a pair of active sufaces is provided by using a Peltier element operating with a DC source having selectively reversible polarity whereby one surface is cooled down while the other is heated and vice versa, depending on instant polarity of the DC source.  In another embodiment, the active surface is alternately heated and cooled by heat carrier medium of a heat pump circulation system drawn from the respective sections of the system in alternating fashion.  Due to the formation of crystallization seeds from the heat storage substance, problems normally associated with the use of a foreign inoculation substance are avoided.           Prior Art The invention relates to a method for inoculating or introducing crystal seeds into a liquid latent heat storage medium convertible to the solid state on cooling, and to an apparatus for carrying out the method.   In liquid latent heat storage media of the type convertible to the solid state on withdrawal of heat, it is essential that at the withdrawal of heat crystal seeds

Abstract: RCA 76,533 Abstract of the Disclosure A frequency selective chrominance signal translating circuit for use in a color television receiver employing a comb filter is disclosed.  The comb filter responds to switching signals for providing separate outputs from which the luminance and chrominance television signal components are derived.  The translating circuit includes first and second cascaded, bandpass filters tuned to frequencies above the chrominance subcarrier frequency. The first filter receives comb filter output signals including desired chrominance signals and undesired components at the frequency of the comb filter switching signal.  The circuit prevents unwanted high frequency components, particularly those associated with the comb filter switching signals, from reaching the color demodulators of the receiver, and translates signals from the chrominance output of  the comb filter for supplying chrominance signals to color demodulators with a substantially symmetrical amplitude response and linear phase response as required for proper color demodulation.

Abstract: ABSTRACT A method is described for determination of single enzymatic activities of the cytoplasmatic and mitochondrial isoenzymes of Glutamic Oxalacetic Transaminase (GOT) in samples of serum or plasma.  The GOT activity present in serum or plasma is determined before and after incubation with L-serine-o-sulphate to obtain in the first case an enzymatic activity value corresponding to the total sum of activity of the two isoenzymes, and in the second case a value of enzymatic activity corresponding to the activity of only the mitochondrial enzyme, the activity of cytoplasmatic isoenzyme being obtained from the difference of the two above mentioned values.  It is useful in clinical diagnoses.

Abstract: ABSTRACT        A process for the recovery of cyanide from thiocyanate.  An  aqueous solution containing thiocyanate is introduced into an electrochemical reactor.  The reactor is activated for an appropriate time period while the pH of the solution is maintained in the range of 1 to 4.  The cyanide formed can be recovered, in various ways including recovery as hydrocyanic acid.  Where desired, the thiocyanate can be oxidized in the reactor for a longer time period while the pH of the solution is maintained in the range of 10 to 12, to produce relative-ly harmless products, for example cyanate, ammonia, carbon dioxide and nitrogen.        The process is particularly useful to process thiocyanate containing wastes produced in the processing of gold and silver ores and concentrates, unit operations related to base metal processing, coking operations and petroleum refining.

This potty seat is designed to be mounted to the toilet seat of a toilet bowl.  An important feature of this invention is that the mounting means for the potty seat is located toward the rear of the seat so that when the seat is inverted and positioned on the floor in front of the toilet bowl, the mounting means does not constitute an obstruction which would make it difficult for a child to stand on the inverted potty seat in the manner of a step stool.  The rear portion of the potty seat is specially designed so that when the seat is used as a step stool, the stool may be positioned closely adjacent the front of the toilet bowl so that a small boy may reach the toilet bowl.  In other words, the inverted potty seat has a telescoping relationship with the base of the toilet bowl.

Abstract: ABSTRACT          NEAR-ZERO MAGNETOSTRICTIVE GLASSY METAL ALLOYS WITH HIGH MAGNETIC AND THERMAL STABILITY           . A new series of glassy metal alloys with near-zero magnetostriction is disclosed.  The glassy alloys have the composition CoaFebNicModBesif, where a ranges from about 58 to 70 atom percent, b ranges from about 2 to 7.5 atom percent, c ranges from about O to 8 atom percent, d ranges from about 1 to 2 atom percent, e ranges from about 11 to 15 atom percent and f ranges from about 9 to 14 atom percent with the proviso that the sum of a, b, c ranges from about 72 to 76 atom per-cent and the sum of e and f ranges from about 23 to 26 atom percent.  The magnetostriction of these alloys ranges from about -1 x 10-6 to +1 x 10-6 and the saturation induction is between about 0.6 and 0.8 Tesla.  The transition metal content is responsible for the low magnetostriction in these alloys.  The metalloid content strongly affects the saturation induction, Curie temperature, and magnetic stability. Magnetostriction is mildly affected by the metalloid composition and a particular range of Si/B ratio for cértain iron, cobalt containing alloys wherein the magnetostriction is near-zero and relatively insen-sitive to the Si/B ratio.  The same Si/B ratios also provide  high magnetic stability.
